Molded Case Circuit Breakers

Molded case circuit breakers are between air circuit breakers and miniature circuit breakers, they are widely used in many fields, such as industrial fields, the field of architecture, water conservancy and hydropower.

Molded case circuit breakers are mainly installed in low-voltage cabinet used as intermediate distribution using, some in small distribution box or mounted directly on the wall as the direct distribution of some of the loads.

Molded case circuit breaker with air circuit breaker and leakage circuit breaker, generally have three types, one with short circuit and overload protection function. Two, with leakage protection function. Three, with short circuit, overload, leakage protection function. Can protect lines and power equipment from damage.

With overcurrent tripping device, undervoltage release (or delay), shunt tripping device, locking and tripping device. Appropriate decision switch, general protection transformer and large capacity power distribution line. With the handle, the lever, the electromagnet, the motor, the air pressure, the hydraulic energy storage type, the non energy storage type and the intelligent operation and so on.
